CHARLES L. FREVERT, OF MINIEB ILLINOIS.

RAILWAY-TIE.

To all whom it may concem:

Be it known that I, CHARLES L. FREVERT, a citizen of the United States, residing at Minier, in the county of Tazewell and State of Illinois, have invented certain new and useful Improvements in Railway-Ties, of which the following is a specification.

This invention relates to improvements in reinforced concrete cement ties and chair appliances and particularly embraces certain improvements in the constructions patented by me on Dec. 21, 1909, Patent Number %3,926.

One of the objects of the present invention is to provide improved means for securing the chair to the reinforced concrete cement tie.

Another object of the invention is to improve the general structure of the reinforcing means embedded in the concrete cement ties.

lVith the above and other objects in view the invention comprises certain combinations, constructions and arrangements of parts, clearly described in the following specification and clearly illustrated in the accompanying drawings forming a part of the specification and wherein,

Figure l is a longitudinal sectional view illustrating the improved reinforcing tie bar and the improved chair, Fig. 2 is a plan View thereof, Fig. 3 is a cross sectional view showing the construction of the chair more completely, and Fig. 4 is a plan view of one of the chairs.

Referring to the accompanying drawings illustrating the invention 1 clenotes a concretc cement tie in which a longitudinally disposed reinforcing netal bar 2 is embedded. On top of the tie l the rail chairs 3 are positioned. These chairs are provided with depending legs 4:, two of which eXtend from opposite sides of each chair and are connected to the reinforcing bar 2 by means of transversely disposed rods or bolts 5. A portion of each leg t engages the side of the Specification of Letters Patents.

bar 2 while the entire body of each leg is embedded in the concrete cement of which the tie is composed.

The method of securing the chairs to the reinforcing bars eil'ectively unites the various parts of the device so as to produce an eificient unitary structure. The chairs 3 are formed with rail engaging ribs or lugs 6, which are curved to fit the longitudinal lower edge of the rail 7 and are provided with a base portion 8 which is eXtended laterally of the rail to engage the plate 9, which is connected to said base 8 by means of a bolt 10. The bolt 10 also serves to connect the tie bar ll, which is provided with ofiset ends 12, whereby the central part of the tie bar will lie snugly against the upper surface of the rail tie.

By means of the improvements the various parts shown in the patent issued to me on Dec. 31, 1909, are more effectively united to each other and to the concrete cement tie so as to give better service. Two embedded reinforcing tie bars 2 may be employed, if desired. The ends of the bar 2 are eXtended at 13 beyond the ends of the tie 1, whereby a series of ties may be locked together by a connecting rod passed through said eX- tended ends of the tie bars 2. The other constructons shown in the above patent may be employed in connection with the constructions here shown and described.

Having described my invention I claim A cement tie, a tie rod embedded therein, chairs having depending angular legs seated on the tie with the legs embedded in said tie, bolts connecting the legs to the tie rod, said legs being oppositely inclined, and clamping plates for the chairs.

In-testimony whereof I affix my signature in presence of two witnesses.

CHARLES L. FREVERT.
